I just finished The Testosterone Syndrome by Eugene Shippen and William Fryer.  It was an interesting book about reversing the aging process in men with an aside on women.  The author’s premise is that low testosterone is the major factor in male aging, such as low sex drive, apathy, aches and pains, weaker muscles, slower healing, prostate cancer, less cognitive function (whereas some would argue that testosterone is the reason we men don’t think very well at times, but I digress), cardiovascular disease, erectile dysfunction, urination problems, headaches, insomnia, depression among other issues.  They make a good case for testing men’s hormone levels, and doing the things to maintain a decent balance.  They also hit on one of the things I think get ignored too much in taking care of men: estrogen levels.  Yes men do have estrogen, and yes it is essential to their health, but not at the levels needed for women’s health.  One thing that non-body builders don’t understand is that testosterone can be converted by the body to estrogen. This is done by enzymes called aromatase.  Sadly, as we age we tend to get less active, this leads to less muscle, and a higher body fat.  Fat cells are one of the big culprits for converting testosterone to estrogen.  They have plenty of aromatase activity.  Too much alcohol also increases men’s estrogen to testosterone ratio, which is not what we want.  Zinc deficiency is also a contributor to the problem, as well as a bunch of other health problems, but more on that later.  Liver issues, drugs, and estrogen from food also can contribute.  
What do we do?  
First, since the liver is in charge of getting rid of the excess estrogen, we should take good care of it.  It is the main detoxification organ, so less useless work makes it better able to do necessary work.  Exposing your self to a plastic, hormone/antibiotic filled garbage diet leaves a lot more work for the liver than a diet of whole natural chemical free food.  This includes all unnecessary drugs including the ever popular statins that everyone seems to be getting a script for.  Since these work by slowing down the liver’s function how well do think that helps your ability to detoxify?  If my cholesterol got to 900 I wouldn’t take statin drugs, I would, however, work my backside off to lower it.  But, again, I digress.  
Second, Exercise!  Having more muscle helps.  Resistance training seems to help increase testosterone.  It also lowers body fat, which helps lower aromatase activity.  It is the best way to get rid of the “need” for statin drugs for most people also.  Exercise also helps the heart, which we all know.  It also helps the brain function, which many people don’t know.  How? By increasing blood to the brain, by stabilizing blood sugar, by hormone releases that increase cognitive function.  It has huge and diverse benefits, and is the one cheapest, most effective thing one can do for heart disease, diabetes, and bunches of other health issues.  If you are not doing it regularly, then Ask your Doctor if getting off your Butt is right for you!  If you have musculoskeletal issues, you may do well to consult your Chiropractor before starting.  
Third a decent vitamin regiment is called for.  Zinc is required for so many things in the body.  It is a major factor in proper digestion, proper pituitary function [the part of the brain that directs the whole hormone balance], prostate and reproductive health, the ability to taste, and lots more.  One sign of zinc deficiency is indigestion.  It seems half the population is on the ‘purple pill’ or some other stomach drug, even newborns for ‘reflux.’  One thing the TV does not tell is that antacids lower your body’s ability to digest and absorb iron, protein, and calcium, among other things.  If you become anemic and don’t get enough protein, and have osteoporosis how good is your life going to be?  Maybe fixing the digestion is a better idea?  Zinc will likely be part of the solution.  
Vitamin C is also one of those things that do everything in the body it seems.  Everyone has heard it helps the immune system [whose job it is to protect us from cancer cells growing in our body,] but it also is a great antioxidant.  It seems to help replenish the other antioxidants.   
B12 and Folic acid are also important B vitamins that help lower homocysteine, which is a better marker of heart issues than cholesterol.  They are also important to red blood cell production.  B6 helps in the pituitary, which is the part of the brain controlling hormones.  Taking a good source of B complex is important.
Vitamin E is another well known antioxidant and all around important to everything vitamin.  It too is essential.
What does all this mean?  If you want to live a long and healthy life, put in good fuel, don’t put in a bunch of chemicals, and move around every day.  If you are just getting started with that, you may want to have a health coach with the heart of a teacher to help you along.  This can be your Chiropractor, Naturopath, Nutritionist, Trainer, Primary Care Provider, or some combination of them on your team.  Make some positive changes to you life every week.
